A Class of N-body Problems With Nearest And Next-to-Nearest Neighbour Interactions
We obtain the exact ground state and a part of the excitation spectrum in one dimension on a line and the exact ground state on a circle in the case where N particles are interacting via nearest and nextto-nearest neighbour interactions. Further, using the exact ground state, we establish a mapping between these N -body problems and the short-range Dyson models introduced recently to model inte...
متن کاملSpin chain under next nearest neighbor interaction
We perform a numerical study on the concurrence of the ground state Heisenberg XXX with next-nearest-neighbor interaction with open and periodic boundary condition.
متن کاملContinuous- and First-order Phase Transitions in Ising Antiferromagnets with Next-nearest- Neighbour Interactions
Both the square and triangular Ising antiferromagnetic systems with next-nearest neighbour interactions are studied by a new efficient entropic scheme. Using the energy distribution and order parameter’s fourth order cumulant it is illustrated that the two models behave quite differently. For the square model we establish strong numerical evidence showing a continuous transition scaling, wherea...
متن کاملPhase transitions in the two-dimensional superantiferromagnetic Ising model with next-nearest-neighbor interactions.
We use Monte Carlo and transfer matrix methods in combination with extrapolation schemes to determine the phase diagram of the two-dimensional superantiferromagnetic (SAF) Ising model with next-nearest-neighbor (NNN) interactions in a magnetic field. The interactions between nearest-neighbor (NN) spins are ferromagnetic along x, and antiferromagnetic along Y. We find that for sufficiently low t...
متن کاملCrossovers in the two-dimensional Ising spin glass with ferromagnetic next-nearest-neighbour interactions
By means of extensive computer simulations we analyse in detail the twodimensional ±J Ising spin glass with ferromagnetic next-nearest-neighbour interactions. We found a crossover from ferromagnetic to ‘spin glass’-like order both from numerical simulations and analytical arguments. We also present proof of a second crossover from the ‘spin glass’ behaviour to a paramagnetic phase for the large...
